[GRASS-user] Feet-to-Meter Conversion

[Rich Shepard]

   The standard conversion factor from feet to meters is 1 ft = 0.3048 m.
However, the conversion factor for US Survey Feet (frequently the distance
unit in the US State Plane Coordinate System) is 1 US ft = 0.3600 m.

   I don't know the magnitude of the error when GRASS assumes international
feet (0.3408) as the conversion factor. When I have a project location in
SPCS is there any harm in manually changing the PROJ_UNITS from 0.3048 to
0.3600?
